Title: The Innovative Contributions of Jacques B Lechat
Introduction
Jacques B Lechat is a notable inventor based in Wezembeek-Oppem, Belgium. He has made significant contributions to the field of hydrocarbon resins, particularly in their application in adhesives. With a total of 4 patents to his name, Lechat's work has had a considerable impact on the industry.
Latest Patents
Lechat's latest patents include innovative formulations of hydrocarbon resins. One of his notable inventions is titled "Novel hydrocarbon resins and their use in adhesives." This patent describes hydrogenated hydrocarbon resins derived from cyclopentadiene and/or substituted cyclopentadiene. These resins have a softening point below 90 degrees Celsius and a glass transition temperature (Tg) ranging from 35 to 70 degrees lower than the softening point. They contain less than 12 wt. % of the resin with a molecular weight above 1000, making them particularly useful as tackifiers in pressure-sensitive adhesives. This innovation is especially beneficial in hydrogenated styrene/butadiene/styrene block copolymer adhesive formulations, where it can eliminate the need for plasticizing oil. Another significant patent is "Petroleum resins and their production," which focuses on resins that exhibit an improved combination of softening point and tackifying properties, along with good color and heat stability. These resins are obtained through Freidel-Crafts copolymerization of a C5/C6 unsaturated feed and 5 to 30 wt. % of para methyl styrene.
